Description

Die Erfindung betrifft eine Gitterstruktur nach dem Oberbegriff des Anspruchs 1.The invention relates to a lattice structure according to the preamble of claim 1.

Gitterstrukturen dieser Art werden als Bauelemente in Gestalt von flachen oder gewellten Trag- oder Schutzgittern eingesetzt, wobei die Schubfestigkeit der Knotenpunkte sicherstellt, dass das Gitter auch bei hohen Belastungen nur geringe Verformungen erfährt. Zum Verbinden der Drähten in den Knotenpunkten werden bisher Schweissverbindungen, Klemmen oder zusätzliches Drahtmaterial oder ähnliches verwendet.Lattice structures of this type are used as structural elements in the form of flat or corrugated supporting or protective lattices, with the shear strength of the nodes ensuring that the lattice also with high loads only undergoes minor deformations. So far, welded connections, clamps or additional wire material or the like have been used to connect the wires in the nodes.

Eine Gitterstruktur dieser Art ist in der AT-PS 409 506 B geoffenbart. Sie besteht aus stabförmigen Über- und Untergurten, zwischen denen Verbindungsstäbe eingeschweisst sind. Diese die Knotenpunkte bildenden Schweissstellen bringen einerseits Gefügeänderungen mit sich und verursachen andererseits einen hohen Fertigungsaufwand beim Zusammenschweissen der Gurtstäbe. Letzteres trifft auch bei Verwendung von mechanisch verarbeiteten Verbindungselementen zu, die ebenfalls einen hohen Arbeits- und Kostenaufwand zur Folge haben. GB 172 476 A offenbart eine Gitterstruktur nach dem Oberbegriff des Anspruchs 1.A lattice structure of this type is in the AT-PS 409 506 B revealed. It consists of rod-shaped upper and lower flanges between which connecting rods are welded. On the one hand, these welding points, which form the nodal points, result in changes to the structure and, on the other hand, cause high production costs when welding the chord bars together. The latter also applies to the use of mechanically processed connecting elements, which also result in a high level of work and expense. GB 172 476 A discloses a lattice structure according to the preamble of claim 1.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, diese Nachteile zu vermeiden und eine Gitterstruktur der eingangs genannten Gattung zu schaffen, deren Knotenpunkte keine Schweissstellen oder zusätzliche Materialien aufweisen und sie dabei aber effizient und wirtschaftlich herstellbar ist. Ferner soll auch der Korrosionsschutz der Gitterstruktur dauerhaft gewährleistet sein.In contrast, the invention is based on the object of avoiding these disadvantages and creating a lattice structure of the type mentioned at the outset, the nodes of which have no welding points or additional materials, but which can be produced efficiently and economically. Furthermore, the corrosion protection of the lattice structure should also be permanently guaranteed.

Diese Aufgabe wird erfindungsgemäss nach den Merkmalen des Anspruchs 1 bzw. der Ansprüche 7 und 8 gelöst.This object is achieved according to the invention according to the features of claim 1 and claims 7 and 8, respectively.

Damit entsteht zwischen den Längs- und Querelementen eine unverschiebbare Verbindung, die ohne fremde Verbindungsmittel und mit verhältnismässig geringem Aufwand herstellbar ist. Zusätzlich ergibt sich eine höhere Lebensdauer der Gitterstruktur, da keine schwächenden Schweissstellen oder ähnlichem bei den Knotenpunkten vorhanden sind. Das erfindungsgemässe Gitter lässt sich in verschiedenen Ausführungsformen realisieren. In einer ersten Ausführungsform sieht die Erfindung vor, dass die Längs- und Querelemente des Gitters mit entlang der Elemente vorzugsweise senkrecht zur Gitterebene offenen oder geschlossenen, unverdrillten oder teilweise vorverdrillten Schlaufen versehen sind, die an den Kreuzungsstellen der Elemente miteinander verdrillt sind und so Knotenpunkte bilden. Um dieses Verbinden zu erleichtern, sind die Schlaufen der Längsdrähte in Längsrichtung der Drähte angeordnet, während die Schlaufen der Querelemente quer zur Längsrichtung der Drähte ausgerichtet sind. Es ist aber auch ohne weiteres möglich, umgekehrt die Längsdrähte mit quer zur Längsrichtung der Drähte angeordneten Schlaufen zu versehen, indes die Querelemente mit in Längsrichtung der Drähte angeordneten Schlaufen versehen sind.This creates a non-displaceable connection between the longitudinal and transverse elements, which can be produced without external connection means and with relatively little effort. In addition, the lattice structure has a longer service life, since there are no weakening welds or the like at the nodes. The grating according to the invention can be realized in various embodiments. In a first embodiment, the invention provides proposes that the longitudinal and transverse elements of the lattice are provided with loops that are open or closed, untwisted or partially pre-twisted along the elements, preferably perpendicular to the lattice plane, which are twisted together at the crossing points of the elements and thus form nodes. In order to facilitate this connection, the loops of the longitudinal wires are arranged in the longitudinal direction of the wires, while the loops of the transverse elements are oriented transversely to the longitudinal direction of the wires. Conversely, it is also readily possible to provide the longitudinal wires with loops arranged transversely to the longitudinal direction of the wires, while the transverse elements are provided with loops arranged in the longitudinal direction of the wires.

Die Erfindung sieht vor, dass sich das Gitter aus zumindest doppelt geführten und an den Kreuzungsstellen der Drähte ineinander durchgeführt und mit sich selbst verdrillten Längs- und Querelementen zusammensetzt.The invention provides that the lattice is composed of longitudinal and transverse elements which are at least double-run and are guided through one another at the crossing points of the wires and are twisted with one another.

Hierbei ist es zweckmässig, vorzugsweise die Litzen oder Seile mit entlang derselben verteilten Durchgängen zur Aufnahme der durch sie hindurchgeführten Querelemente zu versehen. Es können aber umgekehrt genauso die Durchgänge in den Querelementen vorgesehen und die Längsdrähte durch die Querelemente hindurchgeführt werden.It is expedient here preferably to provide the strands or cables with passages distributed along the same for receiving the transverse elements passed through them. Conversely, however, the passages can be provided in the transverse elements and the longitudinal wires can be passed through the transverse elements.

Im Hinblick auf die Stabilität des Gitters im Belastungszustand ist es vorteilhaft, wenn die Längs- und Querelemente in einer Ebene liegend rechtwinklig zueinander ausgerichtet sind. Die erfindungsgemässe Bildung der Knotenpunkte ist aber auch ohne weiteres bei Gittern mit anderen Kreuzungswinkeln anwendbar.With regard to the stability of the lattice under load, it is advantageous if the longitudinal and transverse elements are aligned in one plane at right angles to one another. The formation according to the invention of the nodal points can also be used without further ado for gratings with other crossing angles.

Es ist ebenfalls fertigungstechnisch vorsteilhaft, wenn die Abstände zwischen den Knotenpunkten des Gitters in Längs- bzw. Querrichtung gleichmässig sind.It is also advantageous in terms of production if the distances between the nodes of the grid are uniform in the longitudinal and transverse directions.

Erfindungsgemäß sind die Längs- undloder Querelemente zumindest teilweise aus hochfestem Stahl, mit einer Festigkeit von 700 N/mm2 bis 2800 N/mm2 hergestellt.According to the invention, the longitudinal and/or transverse elements are at least partially made of high-strength steel with a strength of 700 N/mm 2 to 2800 N/mm 2 .

Die nicht erfindungsgemäße Gitterstruktur 1 nach Fig. 1 bis Fig. 3 besteht aus Längselementen 2 und Querelementen 3 vorzugsweise aus Stahl, die in regelmässigen Abständen mit senkrecht stehenden Schlaufen 4 bzw. 5 versehen sind. Bei diesen Längs- und Querelementen handelt es sich insbesondere um Drähte Litzen, Seile, Stäbe oder Profile. Es können aber auch Kombinationsprodukte mit Stahl und Kunststoff und/oder Kunststoffprodukte sowie Sandwichelemente davon sein.The lattice structure 1 not according to the invention Figures 1 to 3 consists of longitudinal elements 2 and transverse elements 3, preferably made of steel, which are provided with vertical loops 4 and 5 at regular intervals. These longitudinal and transverse elements are, in particular, wires, strands, cables, rods or profiles. However, it can also be combination products with steel and plastic and/or plastic products and sandwich elements thereof.

Ferner könnten die Querelemente im Vergleich zu den Längselementen im Querschnitt unterschiedlich dimensioniert, aus unterschiedlichen Materialien undloder mit verschiedenen Eigenschaften, wie Festigkeit etc. bestehen.Furthermore, the transverse elements could be dimensioned differently in cross-section compared to the longitudinal elements, consist of different materials and/or have different properties, such as strength, etc.

Eine solche Gitterstruktur 1 eignet sich für verschiedene Anwendungen im Armierungs-, Schutz- bzw. Sicherungsbereich. So können sie beispielsweise für Armierungen in Beton, Asphalt, als Bewehrung im Bergbau oder ähnlichem eingelegt bzw. verwendbar sein.Such a lattice structure 1 is suitable for various applications in the field of reinforcement, protection or security. For example, they can be inserted or used for reinforcements in concrete, asphalt, as reinforcement in mining or the like.

Sie können aber auch für andere Zwecke, wie Böschungssicherungen auf Erdoberflächen jeglicher Art oder auch bei Schutzverbauungen gegen Lawinen, Steinschläge oder gegen andere Naturgefahren eingesetzt werden.However, they can also be used for other purposes, such as securing embankments on any type of earth surface or for protective structures against avalanches, falling rocks or other natural hazards.

Darüberhinaus können solche Gitterstrukturen für Innen- und Aussenanwendungen bei Bauten angewendet werden, so beispielsweise als permanentes oder mobiles Schutz- oder Trennelement, welches in hochfester Ausführung ausserdem die Vandalensicherheit erhöht.Furthermore, such lattice structures can be used for indoor and outdoor applications in buildings, such as permanent or mobile protective or separating element, which, in a high-strength design, also increases vandalism protection.

Diese Gitter sind endlos oder als Paneelen herstellbar und je nach Ausführung rollbar, was die Anwendungsmöglichkeiten erweitert und insbesondere Vereinfachungen bei Transport und Montage ermöglicht.These grids can be produced endlessly or as panels and, depending on the design, can be rolled up, which expands the possible applications and, in particular, simplifies transport and assembly.

Die Drähte dieser Gitterstruktur 1 sind an den Kreuzungsstellen 6 durch Schlaufen 4, 5 miteinander fest verdrillt und bilden damit Knotenpunkte 7, die auch unter Belastung schubfest sind und bei Verformungen des Gitters standhalten. Damit ergibt sich eine Art Formschluss bei diesen Knotenpunkten 7:
Bei dieser Gitterstruktur 1 sind die als Drähte ausgebildeten Längs- und Querelemente 2 bzw. 3 senkrecht zueinander in einer Ebene liegend angeordnet, wobei die Knotenpunkte 7 sowohl in Längsrichtung als auch in Querrichtung mit gleichen Abständen voneinander entfernt sind.The wires of this lattice structure 1 are twisted together at the crossing points 6 by loops 4, 5 and thus form nodes 7, which are shear-resistant even under load and withstand deformations of the lattice. This results in a kind of form fit at these nodes 7:
In this lattice structure 1, the longitudinal and transverse elements 2 and 3 in the form of wires are arranged perpendicular to one another in a plane, with the nodal points 7 being equidistant from one another both in the longitudinal direction and in the transverse direction.

Es ist aber auch selbstverständlich möglich, für beide Richtungen unterschiedliche Abstände vorzusehen. In beiden Fällen ist die Geometrie des Gitters beispielsweise mit der von Betonstahlmatten vergleichbar.However, it is of course also possible to provide different distances for both directions. In both cases, the geometry of the grid is comparable to that of welded steel mesh, for example.

Als weitere Variante könnten die Knotenpunkte 7 nicht annähernd rechteckig, sondern zickzack-förmig ausgebildet sein. In der Praxis ist aber die rechteckige Anordnung sowohl herstellungstechnisch als auch im Hinblick auf ihre mechanischen Eigenschaften als vorteilhaft anzusehen. Zum Befestigen der Gitterstruktur 1 zum Beispiel an einem sie umfassenden Rahmen sind geschlossene Verankerungsschlaufen 8 an den Enden der Längs- und Querelemente 2 bzw. 3 vorgesehen, die ohne zusätzliche Mittel eine rund um das Gitter gleichmässige Befestigung ermöglichen.As a further variant, the node points 7 could not be approximately rectangular, but zigzag-shaped. In practice, however, the rectangular arrangement is to be regarded as advantageous both in terms of production technology and with regard to its mechanical properties. To fasten the lattice structure 1, for example, to a frame surrounding it, closed anchoring loops 8 are provided at the ends of the longitudinal and transverse elements 2 and 3, respectively, which enable uniform fastening around the lattice without additional means.

Fig. 2 a) und b) zeigen einen mit Schlaufen 4 bzw. 5 vorbereiteten Längsdraht 2 bzw. Querdraht 3 und zum Zusammenbau ihrerseits einen ebenfalls zum Zusammenbau mit um 90° quergestellten Schlaufen 5 vorbereiteten Querdraht. Damit liegen die Schlaufen 4, 5 bei den Kreuzungsstellen 6 vor dem Verdrillen parallel nebeneinander, so dass das Verdrillen einfach ausgeführt werden kann. Fig. 2 a) and b) show a longitudinal wire 2 or transverse wire 3 prepared with loops 4 or 5 and, for assembly, a transverse wire also prepared for assembly with loops 5 positioned transversely by 90°. The loops 4, 5 are thus parallel to one another at the crossing points 6 before twisting, so that the twisting can be carried out easily.

Selbstverständlich können diese Schlaufen auch andersförmig als gezeigt vorgeformt sein. Um den jeweiligen Draht mit den quergestellten Schlaufen könnte zusätzlich mindestens ein weiterer Draht zur Bildung einer Litze gewunden sein, der ohne oder auch mit einer Schlaufe versehen sein kann.Of course, these loops can also be preformed differently than shown. In addition, at least one further wire could be wound around the respective wire with the transverse loops to form a stranded wire, which could be provided with or without a loop.

Fig. 3 a) verdeutlicht eine zum Verdrillen der Schlaufen 4 und 5 vorbereitete Kreuzungsstelle 6, wobei die Drähte 2 und 3 in definiert beabstandeten Rillen 9' einer Montageplatte 9 oder dergleichen eingelegt sind, um ein Positionieren und Festhalten für das Verdrillen derselben zu ermöglichen. Die Rillen 9' sind dabei mit solchen Abständen zueinander in der Montageplatte 9 angeordnet, dass sie den Maschengrössen der Gitterstruktur 1 entsprechen. Fig. 3 a) shows a crossing point 6 prepared for twisting the loops 4 and 5, the wires 2 and 3 being inserted in defined spaced apart grooves 9' of a mounting plate 9 or the like in order to enable them to be positioned and held for twisting. The grooves 9 ′ are arranged in the mounting plate 9 at such distances from one another that they correspond to the mesh sizes of the lattice structure 1 .

Fig. 3 b) zeigt die Stelle mit miteinander verdrillten Schlaufen 4 und 5. Sie bilden an dieser Stelle einen unverschieblichen schubfesten Knotenpunkt 7. Fig. 3 b) shows the point with loops 4 and 5 twisted together. At this point they form an immovable, shear-resistant node 7.

Die erfindungsgemäße Gitterstruktur 10 nach Fig. 4 und Fig. 5 a) und b) unterscheidet sich von Gitter nach Fig. 1 hauptsächlich dadurch, dass bei ihm die Längs- und Querelemente 2' bzw. 3' doppelt geführt und nicht die gebildeten Schlaufen, sondern sie jeweils mit sich selbst verdrillt sind, wobei die Längsdrähte 2' in Längsrichtung verteilt angeordnete Durchgänge 11 aufweisen, durch welche die Querelemente 3' geführt sind.The lattice structure 10 according to the invention Fig. 4 and Fig. 5 a) and b) differs from grid to 1 mainly because the longitudinal and transverse elements 2' and 3' are guided twice and not the loops formed, but rather they are each twisted with themselves, the longitudinal wires 2' having passages 11 distributed in the longitudinal direction, through which the Cross elements 3 'are performed.

Fig. 5 a) zeigt einen zum Zusammenbau vorbereiteten Längsdraht 2 mit gleichmässig verteilten Durchgängen 11 zur Aufnahme der Querelemente. Fig. 5 a) shows a longitudinal wire 2 prepared for assembly with evenly distributed passages 11 for receiving the transverse elements.

Fig. 5 b) veranschaulicht einen ebenfalls zum Zusammenbau vorbereiteten Querdraht 3', der zunächst nur bis zur ersten Kreuzungsstelle 6 der Gitterstruktur 10 verdrillt ist. Fig. 5 b) illustrates a transverse wire 3 ′, also prepared for assembly, which is initially twisted only up to the first crossing point 6 of the lattice structure 10 .

Wie aus Fig. 6 a) und b) ersichtlich ist, wird der Querdraht 3' beim Zusammenbau der Gitterstruktur 10 durch den ersten Durchgang 11 des Längsdrahts 2' hindurchgesteckt und anschliessend bis zum nächsten Durchgang weiter verdrillt, wobei er im Bereich der Kreuzungsstelle 6 auch mit dem Längsdraht 2' fest verdrillt wird. Dieser Vorgang wird wiederholt bis der Querdraht 3' vollständig durch sämtliche Durchgänge 11 der Längsdrähte 2' geführt ist. Wenn die Durchgänge 11 entsprechend gross dimensioniert sind, ergibt sich eine in einem bestimmten Winkel verschränkbare und dadurch auch rollbare Struktur.How out Fig. 6 a) and b) As can be seen, the transverse wire 3' is pushed through the first passage 11 of the longitudinal wire 2' during assembly of the lattice structure 10 and then twisted further until the next passage, whereby it is also firmly twisted with the longitudinal wire 2' in the area of the crossing point 6. This process is repeated until the transverse wire 3' has been guided completely through all passages 11 of the longitudinal wires 2'. If the passages 11 are of correspondingly large dimensions, the result is a structure that can be folded at a certain angle and can therefore also be rolled.

Die Gitterstruktur nach Fig. 7 unterscheidet sich von derjenigen nach Fig. 4 lediglich dadurch, dass die Längs- und Querelemente 2" bzw. 3" nur im Bereich der diese ineinandergeführten Kreuzungsstellen 6 verdrillt sind. Ausserhalb dieser Stellen bleiben sie unverdrillt als parallel zueinander geführte Doppel- oder Mehrfachdrähte, die an den Enden auch mit geschlossenen Verankerungsschlaufen 8 zum Befestigen des Gitters an einem ihn umfassenden Rahmen versehen sein können. Die Längs- und Querelemente könnten zwischen den Kreuzungsstellen 6 zwecks höherer Stabilität statt unverdrillt auch miteinander als Litzen mit einigen Windungen gewickelt sein.The lattice structure 7 differs from the one after 4 only in that the longitudinal and transverse elements 2" and 3" are twisted only in the region of the crossing points 6 that lead into one another. Outside of these points, they remain untwisted as double or multiple wires run parallel to one another, which can also be provided at the ends with closed anchoring loops 8 for fastening the grid to a frame enclosing it. For the purpose of greater stability, the longitudinal and transverse elements could also be wound together as strands with a few turns between the crossing points 6 instead of being untwisted.

Die Ausführungsbeispiele nach Fig. 1, Fig. 4 und Fig. 7 können selbstverständlich auch in Umkehrung der beschriebenen Anordnung ausgeführt sein. Bei der Ausführung nach Fig. 1 weisen dann die Längsdrähte 2 quer zur Längsrichtung angeordnete Schlaufen auf, währen die Querelemente 3 mit in Längsrichtung angeordneten Schlaufen versehen sind.The exemplary embodiments 1 , 4 and 7 can of course also be implemented in reverse of the arrangement described be. When running after 1 then the longitudinal wires 2 have loops arranged transversely to the longitudinal direction, while the transverse elements 3 are provided with loops arranged in the longitudinal direction.

Bei den Ausführungsbeispielen nach Fig. 4 und Fig. 7 sind die Durchgänge 11 in den Querelementen 3' bzw. 3" angeordnet, und die Längsdrähte 2' bzw. 2" werden durch die Querelemente 3' bzw. 3" hindurchgeführt.In the embodiments according to 4 and 7 the passages 11 are arranged in the transverse elements 3' and 3", respectively, and the longitudinal wires 2' and 2" respectively are passed through the transverse elements 3' and 3'', respectively.

Fig. 8 zeigt ausschnittweise eine Gitterstruktur 20 mit als Litzen vorgesehenen Längs- und Querelementen 12, 13, die jeweils aus zwei gewundenen Drähten 12' gebildet sind. Es könnten aber genauso mehr als zwei Drähte vorgesehen sein. 8 shows a detail of a lattice structure 20 with longitudinal and transverse elements 12, 13 provided as strands, which are each formed from two twisted wires 12'. However, more than two wires could just as well be provided.

Erfindungsgemäss sind die Querelemente 13 an den Kreuzungsstellen 6 durch Durchgänge 14 bei den Längselementen 12 hindurchgeführt und sie sind damit auf diese Weise durch Ineinanderführen miteinander verbunden. Diese Durchgänge 14 sind dabei durch Öffnungen bei den gewundenen Drähte 12' entsprechend den Maschenlängen gebildet.According to the invention, the transverse elements 13 are passed through passages 14 in the longitudinal elements 12 at the crossing points 6 and they are thus connected to one another in this way by being inserted into one another. These passages 14 are formed by openings in the twisted wires 12' corresponding to the mesh lengths.

Fig. 9 zeigt eine sehr vorteilhafte Herstellung der Gitterstruktur 20 nach Fig. 8, bei der eine Vielzahl von nebeneinander paarweise angeordneten Drähten 12' im Abstand der Maschenlängen von einer Vorrichtung zu Längselementen 12 gleichzeitig gewunden werden. Nach einer Anzahl erzeugter Windungen wird ein jeweiliges bereits gewundenes Querelement 13 zwischen je zwei Drähte 12' der Längselemente 12, die noch nicht gewunden sind, durchgeführt. Anschliessend wird der Windungsvorgang der Längselemente 12 fortgesetzt und dann nach einer gewissen Anzahl Windungen das nächste Querelement 13 in gleicher Weise durch die Drähte 12' geschoben. Anstelle der Längs- könnten Querelemente und umgekehrt angeordnet sein. 9 shows a very advantageous production of the lattice structure 20 8 , in which a large number of wires 12' arranged next to one another in pairs at a distance of the mesh lengths are simultaneously wound by a device to form longitudinal elements 12. After a number of windings have been produced, a respective already wound transverse element 13 is passed between each two wires 12' of the longitudinal elements 12 which are not yet wound. The winding process of the longitudinal elements 12 is then continued and then, after a certain number of windings, the next transverse element 13 is pushed through the wires 12' in the same way. Instead of longitudinal elements, transverse elements could be arranged and vice versa.

Erfindungsgemäß werden diese Querelemente 13 nach dem Einschieben und dem weiteren Windungsvorgang der Längselemente 12 derart mit letzteren verbunden, dass sie zwischen den Drähten 12' eingeklemmt und damit bei diesen Kreuzungsstellen 6 wie Knoten gebildet sind. Damit ergibt sich ein Kraftschluss bei diesen Kreuzungsstellen. Von dieser Vorrichtung zum Winden der Drähte 12' und dem Durchführen der Querelemente 13 sind nur gerade Halterungen 15 am Anfang der Längselemente 12 und Drehmittel 16 schematisch dargestellt. Selbstverständlich könnte diese Gitterstruktur 20 noch anders als oben erläutert hergestellt werden. Erfindungsgemäß sind die fertigen Litzen sowohl bei den Längs- als auch bei den Querelementen 12, 13 mit den entsprechenden Maschenlängen angeordnet und dabei die Längselemente durch maschinell zueinander im elastischen Bereich geöffneten Drähte der gewundenen Querelemente oder umgekehrt durchgeschoben und dann diese geöffneten Drähte wieder losgelassen werden, so dass diese ein Klemmen der durchgeführten Querelemente bewirken.According to the invention, these transverse elements 13 are connected to the longitudinal elements 12 after the insertion and further winding process of the latter in such a way that they are clamped between the wires 12' and thus formed like knots at these crossing points 6. This results in a frictional connection at these crossing points. From this device for winding the wires 12 'and the passage of the transverse elements 13 only straight brackets 15 at the beginning of the longitudinal elements 12 and rotating means 16 are shown schematically. Of course, this lattice structure 20 could also be produced differently than explained above. According to the invention, the finished strands are arranged with the corresponding mesh lengths both in the longitudinal and in the transverse elements 12, 13 and the longitudinal elements are pushed through wires of the twisted transverse elements that are mechanically opened to one another in the elastic area or vice versa and then these open wires are released again, so that they cause the transverse elements that are passed through to jam.

Gemäss Fig. 10 ist eine nicht erfindungsgemäße Gitterstruktur ähnlich wie diejenige nach Fig. 9 ausschnittweise veranschaulicht. Als Querelemente 23 werden anstelle von Litzen einzelne Drähte verwendet, die wiederum durch die Drähte 22' hindurchgeführt sind und so die Verbindung bei den Kreuzungsstellen 6 ebenso mit Vorteil durch ein Klemmen dieser Querelemente 23 durch die Drähte 22' erzeugt ist.According to 10 is a lattice structure not according to the invention similar to that shown in FIG 9 partially illustrated. Instead of strands, individual wires are used as transverse elements 23, which in turn are passed through the wires 22' and the connection at the crossing points 6 is also advantageously produced by clamping these transverse elements 23 through the wires 22'.

Fig. 11 zeigt schematisch eine Gitterstruktur ausschnittweise, wie beispielsweise in Fig. 4 oder Fig. 8 veranschaulicht ist, bei der die Drähte 12' der Längs- bzw. Querelemente 12, 13 verdrillt bzw. zu Litzen verseilt sind. 11 shows schematically a lattice structure in sections, as for example in 4 or 8 is illustrated, in which the wires 12 'of the longitudinal and transverse elements 12, 13 are twisted or stranded into strands.

Diese Längs- bzw. Querelemente 12, 13 sind im Rahmen der Erfindung an den Enden mit benachbarten Quer- bzw. Längselementen 13, 12 verbunden. Im vorliegenden Ausführungsbeispiel sind die Drähte 12", 13" endseitig bei den Längs- bzw. Querelementen 12, 13 abgewinkelt und durch Um- oder Verwinden bei den äussersten rechtwinklig dazu angeordneten Quer- bzw. Längselementen 13, 12 gehalten.Within the scope of the invention, these longitudinal or transverse elements 12, 13 are connected at the ends to adjacent transverse or longitudinal elements 13, 12. In the present exemplary embodiment, the wires 12", 13" are angled at the ends of the longitudinal or transverse elements 12, 13 and are held by twisting or twisting them at the outermost transverse or longitudinal elements 13, 12 arranged at right angles thereto.

Die Längs- undloder Querelemente sind aus hochfestem Stahl mit einer Festigkeit von 700 N/mm2 bis 2800 N/mm2 hergestellt. Damit sind diese Knotenpunkte nach dem Verdrillen noch mit einer höheren Steifigkeit zusammengehalten.The longitudinal and/or transverse elements are made of high-strength steel with a strength of 700 N/mm 2 to 2800 N/mm 2 . This means that these nodal points are still held together with greater rigidity after twisting.

Mit dieser erfindungsgemässen Gitterstruktur lassen sich beliebige Maschenformen bzw. -grössen erzeugen. Im Prinzip könnten diese Längs- und Querelemente auch nicht wie dargestellt rechtwinklig zueinander angeordnet sein, sondern ähnlich wie beispielsweise bei Drahtgeflechten, bei denen rhomboidförmige Maschen gebildet sind.Any mesh shape or size can be produced with this grid structure according to the invention. In principle, these longitudinal and transverse elements could also not be arranged at right angles to one another, as shown, but similar to, for example, wire meshes in which rhomboid-shaped meshes are formed.

Die Längs- undloder Querelemente könnten auch mit um annähernd 360° gebogenen Schlaufen versehen sein, durch welche die Quer- oder Längselemente mit oder ohne Verdrillung geführt sind, wie dies aus den übrigen Figuren ersichtlich ist. Die Knoten bestehen vorteilhaft aus mindestens einer Windung kreisförmiger 360° Schlaufen, die an den vorgesehenen Kreuzungsstellen vorgeformt sind und an den Querdrähten beim Zusammenbau durch Hindurchstecken, Zurückführen und erneut Hindurchstecken durch die Schlaufen der Längsdrähte gebildet werden. Dabei werden die Schlaufen so eingefädelt, dass sie bezüglich der Gitterebene spiegelbildlich zu den Schlaufen der Längsdrähte positioniert sind.The longitudinal and/or transverse elements could also be provided with loops bent by approximately 360°, through which the transverse or longitudinal elements are guided with or without twisting, as can be seen from the other figures. The knots advantageously consist of at least one winding of circular 360° loops which are preformed at the intended crossing points and are formed on the transverse wires during assembly by pushing through, guiding back and pushing through the loops of the longitudinal wires again. The loops are threaded in such a way that they are positioned as a mirror image of the loops of the longitudinal wires with respect to the grid plane.

Es ist ebenfalls möglich, dass nicht sämtliche Kreuzungsstellen mit einer Verbindung, resp. Verdrillung ausgebildet sind. Es können beispielsweise auch nur jede zweite bzw. nach einer Anzahl von Elementen Kreuzungsstellen mit Verbindungen vorgesehen sein, währenddem die übrigen aneinanderliegend angeordnet sind.It is also possible that not all crossing points with a connection, resp. Twist are formed. For example, it can crossing points with connections can also be provided only every second or after a number of elements, while the others are arranged adjacent to one another.
